STOVE.

SPECIFICATION forming part of Letters Patent No. 484,230, dated October 11, 1892. Application filed September 1. 1891. fierial No..404.393. (No model.)

To all whom it may concern:

Be it known that I, 01.01? NI LsoN, of Salt Lake City, in the county of Salt Lake and Territory of Utah, have invented a new and useful Improvement in Stoves, of which the following is a full, clear, and exact description.

My invention relates to an improvement in the construction of stoves, and has for its object to provide a means whereby every portion of the stove calculated to receive dust or soot may be cleaned without soiling the hands or the carpet or fioor upon which the stove stands, and whereby also all of the dust or soot, 850., loosened from the stove may be quickly and conveniently carried to one receptacle located in the stove and removable therefrom.

It is also the object of the invention to so locate the oven with respect to the front, back, top, and bottom of the stove that the heat and products of combustion from the fire-pot may circulate entirely around the oven, and thus insure the'oven baking uniformly throughout its length and breadth.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a central longitudinal vertical section through the improved stove and pipe connected therewith. Fig. 2 is a plan View, the cover being partly broken away. Fig. 3 is ahorizontal section taken, practically, on the line 3 3 of Fig. 1. Fig. 4 is a detail perspective view ofthe ash-pan. Fig. 5 is a detail perspective view of one of the scrapers employed in connection with the stove at the base thereof. Fig. 6 is a perspective view of and at each end of the opening downwardlyflared plates 12 are located, the said plates and the openings 11 being surrounded by a box-like casing 13, open at the front and adapted to receive a removable pan 14 or the equivalent thereof. From the bottom 10 the front and rear walls of plates 16 and 16 and the side walls of plates 15 and 15 extend upward to meet a top 17, with which top they are connected. These plates and the bottom constitute the frame of the stove. The top 17 is provided with the usual opening 18 at its rear near the center, surrounded bya flange or collar 18% to receive the stovepipe 19, and the back plate 16* at its upper central portion is swelled at an angle rearward to its lower portion in a manner to form an inclined chute 20, preferably semicircular in cross-section. The oven 21 is located in the central portion of the stove and extends from side to side.

The upper front portion of the oven is concaved, and the-front plate or wall of the oven is carried upward in front of the concavity essentially flush with the rear upper surface, as is best shown in Fig. 1, forming thereby a fire-pot 22, the front wall of which is straight and the rear concaved. The fire-pot contains anysuitable form of grate 23, and beneath the grate in the fire-pot an ash-pan 24 is removably located, which ash-pan conforms in shape in cross-section to that of the fire-pot and is illustrated in detail in Fig. 5. The ash-pan is capable of being withdrawn from the firepot through a suitable opening produced in one of the sides of the stove.

Between the front plate or wall 22 of the oven and the front of the stove a chamber A is formed, and a wider space is provided between the rear of the oven and the back of the stove, which is divided into two compartments 3 and B through the medium of a vertical partition 25. A space likewise occurs between the bottom of the oven and the bottom of the stove, forming a lower chamber 0, which intersects with the front chamber A and both of the rear compartments B and B, and a similar chamber D is formed above the fire-pot and the oven and the top of the stove. In the upper chamber D at the front of the stove a gate or door 26 is pivoted, operated by a suitable handle 27, as shown in Figs. 1 and 2, which gate or door when carried upward to an engagement with the top of the stove provides for a direct communication between the upper chamber D and the front closed down upon the front wall or plate of the oven and fire-pot this communication is closed. Preferably over the rear portion of the oven in the chamber D a damper 28 is pivoted, operated from the outside of the stove in any suitable or approved manner, and in the upper portion of the partition 25, at the rear of the stove, which partition extends upward to a junction with the top of the stove near the front of the pipe-opening, an opening 29 is produced, which may be closed when desired by a door 30,1nanipulated from the outside of the stove through the medium of an attached handle3l, or in anyother suitable orapproved manner. When the damper 28 is open and the door 30 closed over the opening 29 in the partition 25 and the front door 26 in the chamber D is also open, the products of combustion passing from the fire-pot will be divided, a portion passing down the chamber A into the lower chamber 0 and thence up through the compartment B to the stovepipe 19, while the other portion of the products of combustion passes rearward within the chamber D and down through the compartment B and thence up through the next compartment B. By this means it will be'observed that the products of combustion may be made to circulate entirely around the oven, thereby imparting to it a uniform heat. When a direct draft is desired, the front door or gate 26 is closed, thus preventing the products of combustion from entering the chamber A, the damper is opened and likewise the gate or door 30, and the products of combustion pass only over the top of the oven and out through the opening 29 in the rear partition 25 directly to the stove: pipe. Coal may be poured into the fire-pot through an opening in the front of the stove at the top, normally closed by a door 32.

The prime object of this invention isto provide for the cleaning of every part of the stove and its pipe without removing the latter and without soiling the hands of the operator or the carpet or floor upon which the stove is located. To that end a vertical scraper 33 is located in the chamber A, which scraper consists of-a plate of metal of sufficient width to neatly slide in the said chamber and of a length to extend from a pointwithin the lower chamber 0 to the upper chamber D, as is best shown in Fig. 1. This scraper has attached thereto a rod 34:, which is carried horizontally out through one side of the stove and is provided with a suitable handle, as shown in Fig. 2. Through the medium of the rod 34 the scraper 33 may be laterally reciprocated, and in this reciprocation will remove all dust or soot clinging to the front inner face of the stove-frame and the opposed face of the oven and fire-pot. In each compartment B and B a scraper is also located,designated,respectively, as 35 and 36 and best shown in Figs. 1 and 2. These scrapers act in like manner as the front scraper 33, but do not extend downward into the lower chamber 0. At their upper ends, however, they closely approach the top of the stove. In order that the rear scrapers 35 and 36 may not interfere with the currents of heat, the said scrapers are made as much as possible in the shape of skeleton frames, or the plates from which the scrapers are made may contain a series of openings or apertures.

The scrapers 35 and 36 have each attached thereto a rod 37, which rods, like the rod 34 of the forward scraper, extend outward through one side of the stove. Within the bottom chamber (1 a horizontal scraper 38 is located, which rests upon the bottom of the stove and extends from side to side. This scraper is of suflicient height to engagewith the bottom of the oven at the same time that it engages with the bottom of the stove proper, and the lower scraper is manipulated, preferably, through the medium oftwo rods 39, one being attached at each end of the scraper, and the rods are carried out beyond the front of the stove.

Ascraper 40, differing in construction from the scrapers heretofore described, and illustrated in detail in Fig. 9,'is employed to clean the chute-section 20 at the back ofthe stove. This scraper usually consists of a semicircular foot 41, conforming to the inner contour of the chute-section, and a shank-section 42, connected with the foot, which shank-section extends outward through the top of the stove at the back of the flange surrounding the pipeopening 18 therein, and this scraper is normally held with its foot near the top by hooking or otherwise connecting the upper end of its shank to the pipe 19, as best shown in Fig. 1. The scraper 38 in the lower chamber 0 is preferably provided with an opening 43, extending from end to end and of a width and length to give the scraper the appearance of a skeleton frame, as shown in Fig.

The stove may be cleaned while in place and with the fire burning. The operation is as follows: The top of the oven is swept offand the sweepings drop down the compart-' ment B into the bottom chamber 0. The front and rear scrapers 33, 35, and 36 are then reciprocated until the front chamber A and both 'rear compartments B and B are cleaned, the soot and dust dropping into the in said chamber has been delivered through the opening 11 in the bottom of the stove into the pan 14 beneath the bottom. The pan may then be readily removed from the stove, emptied, and replaced.

When the dampers and draft-chambers are located as above set forth, the oven is not only heated evenly, but as the flames and products of combustion may be made to pass in opposite directions from the fire-pot a vessel located in a stove opening over the fire-pot will have its entire bottom subjected to the action of heat.

I do not claim the stovepipe and its appliances in this application.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A stove comprising the outer frame, an oven Within the frame, fines or chambers A B O D between the front and rear ends and bottom and top, respectively, of the oven and frame, a fire-pot at the upper forward corner of the oven, an ash-pit beneath the fire-pot and having a door in the side of the stove, a damper 26 at thejuncture of chambers or fines A D, a fine or chamber B between the rear wall of the frame and the flue or chamber B and communicating with the chamber or fine O, a damper 30 in the upper end of the partition 25, which separates the fines or chambers 13 B, and a smoke-outlet in the top of the frame over the fine or chamber B, the said fines or chambers B B being the full width and height of the oven and bothopening at their lower ends directly into the rear end of the single undivided chamber 0, substantially as set forth.
